摘　　要：一般的MIMO系统,MIMO-OFDM系统和MIMO MC-CDMA系统是未来宽带无线通信业务发展的候选技术,MIMO技术的研究已经成为通信理论的前沿领域。多径传输会引起频率选择性衰落,码间干扰等许多问题,分别在单用户和多用户条件下,检验多径信号传输对MIMO系统信道容量的影响。Conventional MIMO system, MIMO- OFDM system and MIMO MC- CDMA system are considered as candidates for future broadband wireless services, and they have become the fore field of theory. Multipath propagation can raise many problems such as frequency selective fading, inter symbol interference. In this paper the effects of multipath signal propagation on the capacity of MIMO system, under both single and multiuser channels, are examined.

关 键 词：多输入多输出 多输入多输出多载波码分多址 信道容量 码间干扰
